Specification of Letters Patent.

Patented May 26, 1908.

Application filed April 15, 1907. SerialNo. 368,410.

To all whom it may concern:

Be it known that I, GEORGE WILBUR SPENCER, a citizen of the United States, and a resident of Atlantic City, in the county of Atlantic and State of New Jersew, have invented a new and' Improved Bushing, of which the following is a full, clear, and exact description.

The invention relates to bushings used in connection with devices for tapping kegs, barrels and other receptacles containing sparkling liquids, and its object is to provide a new and improved bushing, arranged to form a very tight joint between the tapping device and the wall of the bung hole, to prevent leakage.

The invention consists of novel features and parts and combinations of the same, which Will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a side elevation of the improvement in position on the driving device, and arranged over the head of the receptacle, the said head being shown in section, Fig. 2 is a sectional side elevation of the same in position on the head of the receptacle, Fig. 3 is a perspective view of the bushing, and Fig. 4 is a sectional side elevation of the same.

The improved bushing consists of a shell or a body A made of paper or other suitable compressible material, the shell being frustoconical in form and its base end A being open and its apex end A2 being closed, the apex end A2 extending inwardly, as plainly indicated in Fig. 4. The wall of the shell A, between the ends at approximately its longitudinal center, is provided with perforations A3, to permit the shell to separate when driven home, as hereinafter more fully described. The shell A is adapted to fit onto the conical part Bl vice B employed for driving the bung or cork O inward in the head D of the keg, barrel or other receptacle to be tapped, it being understood that when the driving de- .of the tapering portion mit rupture of the shell of the usual driving del vice B with the shell A thereon is kdriven home, as illustrated in Fig. 2, then the shell A fits into the bung hole and the tapping can now be completed by forcing the usual tapping pipe E through the driving device and against the end A2 so as to perforate the same and to pass into the contents of the receptacle. N ow during the driving home of the driving device B, the shell A is strained to a considerable extent by the end B abutting against the closed end A2 of the shell A, and consequently the shell A is liable to be torn apart along the perforations A3, but at the same time the outer portion of the shell A is driven tightly in contact with the wall ofthe bung hole, so as to form an exceedingly tight ljoint between the wall of the bung hole and the tapering portion B of the driving device It is understood that when the inner end portion f the shell A is strained and torn, the outer portion is not seriously aected to cause leakage, as is so frequently the case with bushings heretofore constructed.

It will be noticed that applicants device is a frusto-conical shell having its larger end open to receive the driving device, and that the said shell is partially separated or provided with a weakened annular line at approximately its longitudinal center to peron the line of this partial separation during the driving, in order to prevent longitudinal rupture of the upper part of the shell by the driving device.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

l. In a device for tapping barrels, a frustoconical shell having its large. end open to receive the driving device, said shell having an annular series of perforations at approximately its longitudinal center, to permit the rupture of the shell on the line of perforation during the driving to prevent longitudina'l rupture of the upper part of the shell by the driving device.

' 2. In a device for tapping barrels, a frustoconical shell having its large end open to receive the driving device, said shell being provided with a weakened annular line at 1 name t0 this specification in the presence of approximately its center tO permit the ruptwo subscribing witnesses. ipre of tile shell On the weakened line during GEORGE TILBUR SPENCER 1e driving to prevent longitudinal rupture 5 of the upper part Of the shell by the driving device.

In testimony whereof I have signed my Witnesses:

ISAAC M. BROOKE, E. H. BROOKE.
